POINT-PROTECTING ATTACHMENT TO LEAD 0R CRAYON HOLDERS.

SPECIFICATION forming part of Letters Patent No. 271,136, dated January 23, 1883.

Application filed September 21, 1882. (No model.)

on Holders, of which the following is a specitication.

This invention relates to that class of lead or crayon holders which are provided with sliding sleeves to form pencil-point protectors.

The object of my invention is to provide a simple and efficient pencil-point protector for that style of lead or crayon holder having at one end of a handle a clamping-cap for acting on the jaws of a lead-receiving tube.

The object of my invention is accomplished by the construction and combination of parts illustrated in the accompanying drawings, in which- Figure 1 represents a longitudinal section when the pencil-point protector is moved out. Fig.2 is a side view of the same when the pencil-point protector is moved back. Fig. 3

is a sectional side view of the same, showing the friction-spring.

Similar letters indicate corresponding parts.

In the example shown in the drawings, the handle A is provided with a bore extending throughout its entire length. On the front end of this-handle is firmly secured the clamping-cap B, and on the rear end thereof is fastened a ferrule, 0, provided with a screwthread, 0.

D is a tube intended for the reception of the lead. The front end of this tube is split to form the lead-retaining jaws e, and on the rear end of said tube is firmly secured a cap, E, with an internal screw-thread, d, adapted to fit the screw-thread don the ferrule 0. When the cap E is turned so as to advance the tube D in the handle A the jaws E are closed by the inner tapering surface of the clampingcap B, so as to grasp the lead contained in the tube D, and if the cap E is turned so as to retract the tube D, thejaws 0 will open and release the lead.

0n the handle A, near its front end, is fitted a sleeve, F, so as to be capable of sliding iuor out, and the sliding motion of this sleeve is checked by friction-sprin gs f, Fig. 2, which friction-springs extend from a ring, g, which is firmly secured to the clamp-cap B beneath the sleeve F. The front end of the sleeve F is drawn in to form a shoulder, h, and on its 5 rear end is formed an inwardly-projecting flange i, so that the sliding motion of said sleeve on the'handle is confined within certain limits, its outward movement being limited by its stop-flange 5 coming against the ringg on the clamping-cap B, while its inward movement is limited byits shoulder it coming against the front end of the clampingcap.- When the lead is firmly grasped by the jaws e and the sleeve is moved back to the 6 position shown in'Fig. 2, the pencil can be used for writing or other purposes; but if the sleeve is pushed forward tothe position shown in Fig. 1, it forms a perfect pencil-point protector. The forward movement of the sleeve can be effected by placing the cap E upon a table and pressing the sleeve backward. The friction-springs retain the sleeve in any position which it may occupy, and said sleeve is not liable to change its position spontaneously.

It is obvious that the mechanism for retaining and releasing the lead can be changed in many ways without departing from my invention.

I do not claim in this application for a pat- 8; out the construction of theinechanism for 'reraining and releasing the lead which I have herein described, such forming the subjectmatter of a separate application bearing even date with this.

What I claim as new, and desire to secure by Letters Patent, is-

Thecombination, in a lead or crayon holder, of the handle A, the clainping cap B, secured to the front end of the handle, and constructed with a ring, g, and attached frictionspringsf, and the sleeve F, arranged. to slide on the clamping-cap and having its rear end constructed to form a stop to act against the ring on the cap, substantially as described.

In testimony whereof I have hereunto set my hand and seal in-thc presence of two subscribing witnesses.
